Hello Edgewound,
I've just bought two original JBL D8R035TIA diaphragm replacement.
The kit comes with two "rubber" circles, the bigger (dia mm.22) seems to be foam, the other one (dia mm.6) is made with harder material. I think the foam has to be fitted between center magnetic pole and titanium dome (n°1 in thios drawing

Thank you very much,
best regards
Marcello
